L-mm Patent No. 100,372 dated March 1, 1870.

CHIMNEY-COWL.

The Schedule referred to in these Letters Patent and making pan: of the lame.

To all whom it may concern Be it known that I, ELISHA P. H. CAPRON, of the city of Springfield, county of Clark, and State of Ohio, have invented a new and useful Improvement in Chimney-Caps or Ventilators; "and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to tbeletters of reference marked thereon.

The nature of my invention consists in adapting a' spiral wheel or propeller to the top of a chimney in such a manner that said spiral wheel can never run in the wrongdirection, that being an objection to those now in use.

The object of my invention is 'to' produce a cheap chimney-cap or Ventilator that shall effectually cure smoky chimneys by creating a greater draughtv to said chimneys. I V

, To enable others skilled in the art to make and use 4 my invention, I will proceed todescribeits construction and operation. I 1 I p In the accompanying drawings, Figure 1' is a perspective view of my invention, in'ivhich- A is a cap, to shed the storm.

B are the wings, having lips O O to take the wind, effectually preventing the wheel froin'runniug in the wrong direction. I

Said wings B are attached to an upright spindle on shaft H, the ends of which are set loosely in their sockets, so as to allow it to turn with the wind; and

'D is a rib or conductor across the wing, to convey any water "falling upon the wings olf over the edge of the funnel; Y 4 E is a flange or rim attached to the main pipe, leaving a space between for the purpose of preventing the wind from blowing down the chimney flue.

Having thus described my invention,

What Iolaimas new, and desire to secure by Letters Patent, isl 1 1. A spiral wheel or propeller, the wings of which are provided with lips 00, when constructed and arranged substantially as and for the purpose set forth.

2. The rib or conductor D across the wing, substantially as and for the purpose set forth.

3. 'lhe lips O C and rib D, in conneotionvwit-hthe flange E'and cap A, substantially as and for the purpose set forth.
